Hypothesis
What are the risk factors that influence mortality in patients with periprosthetic femur fractures after total hip arthroplasty?
Conclusion
Surgical treatment during regular working hours is associated with lower mortality compared to surgery outside these hours.
Supporting Evidence
- The one-year mortality rate was found to be 23.4%.
- Mortality increased by 12.9% for each additional year of age.
- Surgical treatment during regular hours reduced mortality by 53.2% compared to on-call surgeries.
- Patients with cardiovascular disease had a higher mortality risk.
- Dementia was associated with a significantly increased mortality risk.
Takeaway
This study found that when people have hip fractures after surgery, those who get treated during the day tend to do better than those treated at night.
Methodology
The study analyzed 158 patients treated for periprosthetic femur fractures after total hip arthroplasty between 2010 and 2020, assessing mortality and risk factors using statistical analysis.
Potential Biases
The study may not account for variations in surgical expertise and resources available in different hospitals.
Limitations
The study's retrospective and monocentric design limits the generalizability of the results to other hospitals.
Participant Demographics
Median age of participants was 81 years, with a majority being female.
